I need to find a movie about a high school teacher. There was a scene when he uses a toy gun to pressure the students to come to class and study. And they were going on a trip. It was funny but not 100% pure comedy (I guess?) I know this sounds impossible to find because there's not a lot of information but if you could help it would be awesome because my boyfriend said it was a really good movie but can't figure out the name and we are trying our best to find it! Thanks everyone!
